x86: restrict keyboard io ports reservation to make ipmi driver work
On some of our (single board computer) boards (x86) we are using an IPMI controller that uses I/O ports 0x62 and 0x66 for a KCS (keyboard controller style) IPMI system interface. Trying to load the openipmi driver fails, because the ports (0x62/0x66) are reserved for keyboard. keyboard reserves the full range 0x60-0x6F while it doesn't need to. Reserve only ports 0x60 and 0x64 for the legacy PS/2 i8042 keyboad controller instead of 0x60-0x6F to allow the openipmi driver to work.
